STREET-SPRINKLING SYSTEM.

To all whom it may concern:

Be it known that I, JAMES I-I. OARMAGK, a citizen of the United States,residing at Oklahoma. city, in the county of Oklahoma and State ofOklahoma, have invented cer-v tain new and useful Improvements inStreet- Sprinkling Systems; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in street sprinkling systems.

One object of the invention is to provide an improved arrangement ofwater conducting pipes by means of which streets may be quickly andthoroughly sprinkled.

Another object is to provide an improved construction of, pipes havingmeans to prevent the same from being pressed below the surface of thestreet, said means also facilitating the passage of vehicles over theupwardly projecting portions of the pipes.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure 1 is a plan view of twointersecting streets showing the, arrangement of my improved sprinklingsystem; Fig. 2 is a vertical longitudinal sectional view on the line 2 2of Fig. l; Fig. 3 s a vertical, transverse sectional view on the line8-3 of Fig. 1.

In the accompanying drawings, 1 and 2 denote two intersecting streets orroadways and 3 denotes the curbing along the sides of the streets. Thestreets 1 and 2 are shown in the present instance as having a surfacepaved with concrete material 4 over which is a layer' of asphalt 5 inwhich the water conducting pipes or tubes 6 of my improved system areembedded.

The tubes or pipes 6 are here shown and are preferably of rectangularshape in cross section and have their main or body portion embedded inthe asphalt and set a slight distance into the concrete material of thepaving. The pipes 6 are provided with a reduced upwardly projectingdischarging portion 7 which extends a suitable distance above thesurface of the street and is pro- -vided on its opposite sides which arever- Specicaton of Letters Patent.

tically disposed with a series of upwardly inclined dischargingapertures or perforations 8. The vertical arrangement 4of the aperturedside walls of the extension 7 provides for the protection of theapertures to prevent their becoming clogged with dirt from the street.

On the opposite sides of the upwardly projecting portions 7 of the pipesbelow the outer ends of the perforations 8 are formed laterallyprojecting stop flanges 9 which engage and rest on the upper surface ofthe paving and serve to prevent the pipes from being pressed or forceddown into the paving material by the passage thereover of heavyvehicles. The upper sides of the ianges 9 are beveled or inclinedupwardly on a slight curve from their outer edges toward the upwardlyprojecting portions 7 of the pipes, thereby facilitating the passage ofvehicles over the projecting portions of the pipes. The pipes 6 may beconnected with a water main 10 or other source of water supply at anysuitable point but are preferably connected to the main 10 at theirpoint of intersection, said connection being preferably made through thebottom or lower side of the pipes. By connecting the pipes with the mainat their point of intersection, the water from the main will be equallydistributed in all directions, throughout the branches of the pipe andfrom the same will be discharged through the perforations 8 in oppositedirections toward the curbing of the streets, thereby thoroughlysprinkling and washing the latter. The size and number of the waterdischarging perforations in the pipes may be varied to accord with thepressure and supply of the water from the main.

From the foregoing description taken in connection with the accompanyindrawings, the construction and operation o the invention will be readilyunderstood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

I-Iaving thus described my invention, what I claim is- 1. In a streetsprinkling system, a series of pipes setin the street pavement andhaving respective extensions projecting above the surface of the street,said extensions having vertically disposed side walls with series ofwater discharging perforations therein, and means for preventing thepipes from being pressed down below the surface of the street.

2. In a street sprinkling system, a series of pipes set in the streetpavement and having respective extensions projecting above the streetsurfacebfslaid extensions having oppositely disposed' vertical sidewalls provided wit-h downwardly and inwardly inclined water dischargingperforations, and spaced flanges formed on the opposite sides of theupwardly extending portions of the pipes to engagejthe upper surface ofthe street and thereby prevent the pipes from being forced down belowthe street surface.

3. In a street sprinkling system, a series of pipes set in the paving ofthe street, and having respective upwardly projecting extensionsprovided on opposite sides with series of water dischargingperforations, stop flanges formed on the opposite sides of saidextensions to engage the surface of the street to prevent the pipes frombeing forced downwardly, said stop flanges having inclined uppersurfaces to facilitate the passage of vehicles over the upwardly extending portions of the pipe.

4. In a street sprinkling system, a series of intersecting pipes set inthe surface of the street, said pipes having reduced upwardly projectingextensions provided with upwardly inclined perforations arranged in theopposite sides thereof, stop iianges formed on the opposite sides ofsaid extensions below the perforations therein to engage the uppersurface of the street and thereby prevent the pipes from being forceddownwardly into the paving of the street, and means to connect saidpipes at their point of intersection with a water main.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JAMES H. CARMACK.
